One deputy killed in attack

DENVER (AP) — Authorities in suburban Denver were investigating what led a 37-year-old man to fire more than 100 rounds in his apartment on sheriff’s deputies, killing one and injuring four others. Two civilians were also injured.

The Douglas County coroner identified the suspect as Matthew Riehl.

A YouTube user named Matthew Riehl posted a YouTube video Dec. 13, saying he wanted to replace Douglas County Sheriff Tony Spurlock and railing against the sheriff and other officers in profane, highly personal terms.

The incident began around 5:15 a.m. at Copper Canyon Apartments, a landscaped apartment complex 16 miles south of Denver.
